This study was conducted to evaluate the association of work posture with cervical spine abnormality toward 106 microwave-oven assemblers. A self-administered questionnaire was used to obtain a general characteristics and a work history of workers. The posture of neck and shoulder joint of workers were measured with video tape recording and the simple X-ray of cervical spine was checked-up to observe the X-ray abnormality including degenerative change, curvature abnormality, disc space narrowing or disc canal narrowing.
The result were as follows.
1. The prevalence of degenerative change among cervicobrachial disorder workers was 44.3% (47 persons), curvature abnormality was 43.4%(46 persons), disc space narrowing was 21.7%(23 persons), and disc canal narrowing was 21.7%(23 persons).
2. The prevalence of degenerative change at cervical spine was increased with the degree of neck flexion(flexed versus neutral ; odds ratio (OR) =2.7), the total work´ posture of neck(mild or severe awkward versus neutral . OR= 1.2, 3.4).
3. The prevalence of degenerative change at cervical spine was increased the right shoulder flexion , the heaviness of the materials carried by the right hand and the degree of awkwardness at the total work posture of right shoulder(p
4. There was no evidence of association between curvature abnormality, disc space narrowing, disc canal narrowing and work posture.
In conclusion the awkward work posture was related with degenerative change of cervical spine among microwave oven assembling workers and the further study in these field must be made to prove the association objectively.
